If your ex calls you every couple of months does that me she still has interest even if she dumped you.

I would say yes because any attention can be good attention. Obviously, girls constantly have dudes trying to get their time so she's got an interest but that doesn't mean it's necessarily going anywhere by chatting with her, probably the opposite. If she dumped you, then it could just be to feel superior that you still connect with her after she pushed you aside. I say test it: the next time she calls, answer but only to let her know that you're on your way out to see someone and she should DEFINITELY call you back 'some time.' When she does, do the exact same thing. And do it again and again until you get an emotional reaction out of her. As long as you can stay calm while she reacts, you've got her and you've also raised your value. Instead of her dumping you, she now has 'made a mistake' in her mind. Bait and switch man
